SCISSORS.

Appication filed March 23, 1920, Serial No. 368,053.

Be it known that I, VALTER C. AMY, a subject of King of Great Britain,residing at Pilgrims Rest, Transvaal, South Africa, have inventedcertain new and useful Improvements in Scissors; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to scissors and the primary object of theinvention is to provide an improved pair of scissors, which can bereadily and easily operated, so as to facilitate. the cutting' of anyarticle and thereby eliminate the manual labor associated therewith.

A further object of the invent-ion is to provide an improved pair ofscissors, which is so constructed that as the same is forced over thesurface the blades will be automatically moved into and out of cuttingposition, whereby an article may be readily and easily severed.

A further object of the invention is to provide an improved pair ofscissors having means operatively connecting the blades together, andmeans carried by one of the blades for engaging the surface so that theblades will be automatically operated during the cutting operation.

A still further object of the invention is to provide an improved pairof scissors of the above character, which is durable and efficient inuse, one that is simple and easy to manufacture, and one that can beplaced upon the market at a reasonable cost.

W ith these and other objects in view, the invention consists in thenovel construction, arrangement and formation of parts, as will behereinafter more specifically described, claimed. and illustrated in theaccompanying drawings, forming a part thereof, in which:

Figure 1 is a side elevation of the i1nproved scissors.

Figure 2 is a section taken on the line 2 2 of Figure 1.

Referring to the drawings in detail, wherein similar referencecharacters designate corresponding parts throughout the several views,the numeral 1 generally indicates the impro-ved scissors which includesthe blades 2 and 3, which are pivotally connected together in theordinary or any preferred manner, as at et. The blade 3 is pro- RenewedApril 19, 1924.

vided with an upwardly extending angular extension 5, the upper end ofwhich is enlarged as at 6 to receive the inner enlarged end of a handle8 which is detachably connected thereto by bolts 9 or the like. Thehandle S is inclined downwardly from the enlarged portion 6 and thenrearwardly as at 9 and is provided with a loop 10, whereby the lingersof the user may be readily inserted in the same. The blade 2 is providedwith a downwardly extending extension 11, which has formed thereon therearwardly extending arm 12, the rear end of which is provided withfinger loops 13. The arm 12 adjacent to theV extension 11 is enlarged asat 14 and is provided with an aperture 15 in which is inserted thereduced end 16 of a sha-ft or axle 17. The reduced end 16 is threadedand receives a neck 18 which'holds the same in position on the bladeagainst lateral movement. The opposite end of the axle is provided withan annular shoulder 19 and a wheel 2O is adapted to be rotatably mountedon the axle and engages the annular shoulder and prevents further inwardmovement of the wheel. This end of the axle is likewise threaded andfitted with a nut 21, which holds the same against movement. Aconnecting rod 22 has the lower end thereof bent inwardly as at 23 andprovided with a reduced threaded portion 24, which is rotatablypositioned in an aperture 25 formed eccentrically of the wheel. A nut 26is fitted on the end and holds the rod 22 eccentrically on the wheel.rlhe upper end of the rod is provided with an inwardly eX- tendingangular terminal 27, which is reduced as at 28 and rotatably mounted ina recess 29 formed in the angular portion 5 of the blade 3. The terminalof the reduced portion is threaded and a nut 30 is lifted upon the same,which holds the link in position.

It can thus be seen that when the scissors is placed upon a planesurface and forced over the same, the wheel will be rotated and thusthrough the medium of connecting rod 22, the blade 3 will be effectivelyoperated and thus cut the material desired to be severed. The handle 8of course can be removed from the extension 5, when the scissors is usedin this manner.

When it is desired to use the scissors in the ordinary manner, thehandle 8 is bolted to the extension 5 and the wheel 20 and theconnecting rod 22 is removed, which allows the scissors to be operatedin the ordinary manner.

From the foregoing description it can be seen that an improved pair ofscissors is provided, which is so constructed that the same can beoperated Without the usual manual labor associated with the operation ofa pair of scissors.

In practice, I have found that the form of my invention illustrated inthe accompanying drawings and referred to in the above description, asthe preferred embodiment, is the most eiiicient and practical; yetrealizing the conditions concurrent with the adoption of my device willnecessarily vary, I desire to emphasize that various minor changes indetails of construction, proportion and arrangement of parts may beresorted to, when required Without sacrificing any of the advantages ofmy invention as set forth.

What I claim as new is:

l. bhears having relatively movable blades, a traction member disposedat one side thereof, a pitman for disposition at the side of said memberopposite to said blades, said pitman having laterally extendin portionsditfering in length, each of sai portions having studs, the stud of oneof said portions pivotally extending through said traci tion member, thestud of the other portion pivotally extending through one of saidblades, shoulders at the Junction of said across the marginal edge ofsaid traction member.

2. Shears having an upper relatively stationary blade, a traction wheelcarried by said stationary blade, a lower blade movable with respect tosaid relatively stationary L blade, and a link connection for saidtraction wheel and relatively stationary blade extending from saidtraction wheel across and above said relatively stationary blade.

3. Shears having an upper relatively stationary blade, a handle arm fromwhich the blade extends upwardly, a traction wheel pivoted to said arm,a lower blade pivoted to said blade provided with an upward angularextension at its rear end, a handle arm extending from said extension tocoact with the iirst mentioned handle arm, and a link connection forsaid traction wheel and extension extending from said traction wheelacross and above the stationary blade to said extension.

In testimony whereof I aiiix my signature in presence of two witnesses.
